便携式土壤检测仪

便携式土壤检测仪是一种用于快速检测土壤养分和酸碱度的仪器。该仪器采用微电子技术和光谱分析技术,能够快速、准确地测量土壤中的氮、磷、钾、有机质、pH值等指标。便携式土壤检测仪体积小巧,重量轻便,操作简单,携带方便,适用于田间地头、实验室等多种环境。

土壤重金属

使用一定的浸提剂浸提土壤时,有效重金属进入溶液,溶液中的重金属可与特定的显色剂反应,生成有色物质使溶液呈现出颜色,溶液颜色的深浅与重金属的含量呈正相关,并服从朗伯一比尔定律。即:E=KXCXL,式中E:吸光度,K:吸光系数,C:溶液浓度,L:溶液厚度,由上式得C=E/KL,设待测液浓度为C2,则当K,L相同时C=E2/E*C1式中E2/E1可由仪器内部测知C1为标准溶液浓度,当输入C1数据后,仪器可自动计算并显示出C2值。
